Benefits of technology

0008] The present invention was completed in view of the foregoing, and it is accordingly an object of the present invention to provide a composition for dyeing ker

Problems solved by technology

The composition of this type is inconvenient to use, and there has been a demand for improvement in their usability.
Moreover, it is known that hydrogen peroxide damages keratinous fiber such as hair, and this has produced dissatisfaction with consumers.
Among these disclosed technologies, however, the peroxidase-containing composition needs hydrogen peroxide on account of the characteristic properties of peroxidase, and hence the resulting composition cannot be of one-pack type.
The uricase-containing composition can be of one-pack type, but it does not solve the basic problem with the use of hydrogen peroxide evolved by the enzyme reaction.
However,

Abstract

A composition for dyeing keratinous fiber which includes incorporated therein an oxidative color-developing substance, an enzyme which reacts with oxygen as a substrate but does not evolve hydrogen peroxide, and a weak reducing agent.

Description

[0001] This application is the national phase under 35 U.S.C. .sctn.371 of PCT International Application No. PCT / JP00 / 08525 which has an International filing date of Dec. 1, 2000 which designated the United States of America, the entire contents of which are hereby incorporated by reference.[0002] The present invention relates to a composition for dyeing keratinous fiber which comprises an oxidative color-developing substance, an enzyme which reacts with oxygen as a substrate but does not evolve hydrogen peroxide, and a weak reducing agent. More particularly, the present invention relates to a composition for dyeing keratinous fiber which is well protected from discoloration of compositions with time.[0003] There are compositions for dyeing keratinous fiber which perform their function by oxidation of an oxidative color-developing substance, which include, for example, hair dyes and eyebrow dyes. Such compositions for dyeing keratinous fiber conventionally employ hydrogen peroxide a...
